DOSBox-X (2017/12/31) is released. DOSBox-x is a branch of DOSBox v0.74. DOSBox emulates an Intel x86 PC, complete with sound, graphics, mouse, joystick, modem, etc., necessary for running many old MS-DOS games that simply cannot be run on modern PCs and operating systems, such as Microsoft Windows XP, Windows Vista, Linux and FreeBSD.

DOSBox-X Changelog:
BIOS now supports loading and executing a user-specified binary blob
At CPU reset, just before POST
Just before booting the DOS environment
Mapper fixed to arrange buttons without cutting off the title, by making them longer if necessary
Mapper now shows you visually which keyboard, joystick, and shortcut buttons are being triggered by hilighting them in the mapper UI
Mapper now shows you joystick input by inverting or partially inverting the joystick buttons in the mapper UI
A divide by zero issue has been fixed in joystick button emulation which may fix the known issue of crashing when pushing a joystick button. #319
